Help Requested

Kate (Amy Jo Johnson's character) has young a son. If I remember correctly, his name in the movie was Sam. But the only character named Sam listed in the IMDb credits is played by Nigel Bennett, who's date of birth is listed as 1949. So obviously, either there's a mistake, or there's more than one Sam in the movie and the boy actor is not listed in the credits - which to me seems unusual since he had several speaking parts.

Does anybody know the young actor's name who played Kate's son?

Thanks for your help!
